Norwegian Los Angeles – London LGW
$546.10 round trip
Jan 31- Feb 7, 2016
This is a great deal if you can board with one carry-on bag at maximum 10kg. Checked bag fee is $42 each way and seat assignments are another $42 each way. That is an additional $168 to the $546.10 fare for $714.10 total. Still a low fare for LAX to London.
High add-on fees are why this is an airfare deal only if you can take it with a 22lbs carry-on bag and a random seat assignment.
